- changed/added the following to the user interface: * double-click an empty area of the battlefield to pass (issue #1070) * new animation image when AI is thinking during a game * play click sound when rotating style/layout dial

- fixed the following bugs: * style/layout dial out of sync on right click (issue #1097) * top decks exception if deck file is missing (issue #1093) * various grammatical errors in effect text (issue #1095 and #1100) * sidebar components repositioning during a game (issue #1102) * Vessel of Nascency does not move cards to graveyard if option is not taken (issue #1094) * Cat Soldier creature token missing the Soldier subtype

Just to confirm - a left double-click on an empty area of the battlefield is equivalent to clicking the action button and a right double-click replicates a shift-click. More info regarding mouse and keyboard shortcuts can be found in the Keyboard Shortcuts wiki page.
